Display Apparatus Proximity-Based Content Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses, such as TVs, struggle to securely and conveniently manage private content from mobile devices when shared among multiple users, often resulting in public exposure of private content due to the lack of effective access control and user account management.
Innovation Solution
A display apparatus equipped with a processor that can pivot between portrait and landscape modes, wirelessly communicate with mobile devices, and utilize identification information to selectively restrict content reproduction based on user proximity and device authentication, ensuring secure access and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user account login is used to protect private content, then content security is improved, but user convenience deteriorates due to the need to remember and input account information
Solution Approach 1:
The system automatically detects mobile devices in proximity and performs authentication based on pre-registered identification information, eliminating the need for users to manually input account credentials. The display apparatus autonomously manages the authentication process by comparing detected devices with registered ones, thereby maintaining security while significantly improving convenience.
2Adaptability or versatility
If the display apparatus shares content from multiple mobile devices, then content accessibility is improved, but privacy protection deteriorates as private content may be exposed to other users
Solution Approach 1:
The system applies different access control policies to different mobile devices based on their authentication status. Authorized devices (those with registered identification information) gain access to private content, while unauthorized devices are restricted. This localized differentiation of access rights enables the display apparatus to share content across multiple devices while maintaining privacy protection for each user's private content.
3Reliability
If the display apparatus restricts content reproduction to specific users, then privacy protection is improved, but device complexity increases due to authentication mechanisms
Solution Approach 1:
The system replaces traditional manual authentication mechanisms (account login, password input) with automatic device detection and identification-based authentication. By utilizing wireless communication to detect mobile devices and comparing their identification information against registered data, the system achieves privacy protection through an automated electronic process rather than complex mechanical or manual authentication procedures.

AI summary
A display apparatus includes a display; a communication circuit configured to communicate with a first external device or a second external device; a storage configured to store a list of a first content group designated to allow sharing by a first user of the first external device, a second content group designed to block sharing by the first user, a third content group designated to allow sharing by a second user of the second external device, and a fourth content group designated to block sharing by the second user; and a processor configured to: selectively process a content list based on detection of the first external device and detection of the second external device through the communication circuit.
